The estimated price tag for the project will likely exceed $41 million, and is part of the Culver Viaduct rehabilitation project, which should be completed by the end of this year.

The 4th Avenue station is also under construction. Inglesby said the project will be finished in May.

“That includes opening up the overpass with windows,” he said. “It’s going to look great.”

The east and west sides of the station feature retail space, and stores should move in sometime in 2014.

The stairwells leading from the street to the underground platform at the 7th Avenue station in Park Slope are next on the horizon for the MTA. The project may start as early as June and will take an estimated six to eight months to complete.
